Summary: Support filters in ozone insight point
Key: HDDS-2071
URL: https://issues.apache.org/jira/browse/HDDS-2071
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Elek, Marton
With Ozone insight we can print out all the logs / metrics of one specific
component s (eg. scm.node-manager or scm.node-manager).
It would be great to support additional filtering capabilities where the output
is filtered based on specific keys.
For example to print out all of the logs related to one datanode or related to
one type of RPC request.
Filter should be a key value map (eg. --filter
datanode=sjdhfhf,rpc=createChunk) which can be defined in the ozone insight CLI.
As we have no option to add additional tags to the logs (it may be supported by
log4j2 but not with slf4k), the first implementation can be implemented by
pattern matching.
For example in SCMNodeManager.processNodeReport contains trace/debug logs which
includes the " [datanode={}]" part. This formatting convention can be used to
print out the only the related information.
